Abstract: A barrier composite having reduced blocking is disclosed. The composite may include a substrate, a barrier layer formed from polyvinylidene chloride disposed on the substrate, and an anti-blocking layer disposed on the barrier layer. The anti-blocking layer may be formed from polyvinyl alcohol, and optionally, colloidal silica, wax, or a combination thereof. Alternatively, the anti-blocking layer may be formed from a polymeric carrier material, colloidal silica, and a wax. Methods for forming such composites and for forming a roll of such composites are also disclosed.

Abstract: A barrier paper has a polymeric layer substantially covering a first side of the paper and an anti-blocking coating on a second side. The polymeric layer has anti-blocking characteristics. A method of making an anti-blocking barrier paper also is provided.

Abstract: A polymer blend, and mono- and multilayer films made therefrom, having improved properties such as heat scaling or puncture resistance, wherein the blend has a first polymer of ethylene and at least one &agr;-olefin having a polymer melting point between 55 to 75° C.; a second polymer of ethylene and at least one &agr;-olefin having a polymer melting point between 85 to 110° C.; a third thermoplastic polymer having a melting point between 115 to 130° C., and optionally a fourth polymer, e.g. EVA, having a melting point between 90 to 100° C.

Abstract: An absorbent article including at least one of a topsheet, an absorbent core, an optional distribution layer and a backsheet, at least one of which comprises at least one layer of an extruded superabsorbent web is disclosed. The superabsorbent webs can be made by heating and mixing blends of thermoplastic resins and absorbent polymers in a continuous process, and then preferably extruding the web. The extruded superabsorbent web can be flat or formed, stretched or unstretched, and coextruded or laminated with or to other materials.

Abstract: A covering for a portion of a body or an object, as well as improved, thin plastic films for use in such coverings, are disclosed. The covering comprises a thin plastic film and a pressure sensitive adhesive contacting at least a portion of, and forming a joint with, the thin plastic film. The plastic film comprises from about 85 to about 95 weight percent plastic, and from about 5 to about 15 weight percent tackifier.Such joints may be found in diapers, adult incontinent briefs, bandages, and other body coverings, as well as packagings for a variety of objects. Such joints exhibit unexpectedly high shear adhesion as compared to conventional joints.

Abstract: A polymer blend and mono-and multilayer films made therefrom having improved properties such as heat sealing or puncture resistance wherein the blend has a first polymer of ethylene and at least one .alpha.-olefin having a polymer melting point between 55 to 75.degree. C.; a second polymer of ethylene and at least one .alpha.-olefin having a polymer melting point between 85 to 110.degree. C. and a third thermoplastic polymer having a melting point between 115 to 130.degree. C.; and optionally a fourth polymer e.g. EVA, having a melting point between 90 to 100.degree. C.

Abstract: An improved release sheet for use in connection with a sanitary catamenial pad is disclosed. The improved release sheet exhibits superior noise, drape, bulk and gloss characteristics due to its method of production. A polyethylenic release material containing silicone capable of being fixed within the surface of the release material is coextruded with at least a base film to provide a film which is also embossed to provide a combination pouch and release sheet with superior physical characteristics. Corona treatment of the release material layer preferably occurs following embossing, but can occur prior to embossing or both prior to and following embossing to fix the silicone within the surface of the release material. In-line recycling of materials provides additional cost advantages.
